Today I switched the link on the website to this new forum after I was satisfied it had started well. The novelty of such change may wear off but I am certain this is the right decision.
The old forum will be available only for 4.9 support. Once there is very little day-to-day discussion it will begin to close so it is up to you to keep it alive! Use it if you want it. Regardless, the content will be available forever. It will never be deleted.
Here is the link: http://dsgamemaker.com/forum
It will take some time for Google to re-index the new forum and also work out that the old forum is no longer in operation. The new address for this forum is dsgamemaker.com/dsgmforum
Thanks for your support.
